Here's another study of connecting rod length (based on a Chevy 400
or 383) that was done by a friend who has a little engineering
experience, Team Leader on the Apollo moon shots. Take it for what
it's worth: http://www.rustpuppy.org/rodstudy.htm
It's one man's study and based on mathematical formulae, not
empirical testing. But his conclusion is that connecting rod length
has only a minimal overall effect on total power.
